The single bidirectional channel handles both positive and negative surges in one package — useful for AC signal lines or DC rails where polarity reversal is possible. Operating temperature spans -65°C to 150°C junction, so it survives thermal cycling in outdoor or industrial enclosures without derating at the cold end. ## DO-214AB SMC package and surface-mount assembly Housed in a DO-214AB (SMC) package, the 1.5SMC150CA-M3/9AT mounts flat on the PCB with the cathode tab as the primary heat path. The SMC footprint is standard across the 1.5SMC series, so a single board layout serves the full voltage range from 5V to 188V standoff. ## Active lifecycle and sourcing posture The 1.5SMC series is a long-running TransZorb® platform with broad distributor coverage, so second-sourcing across the same voltage bin is straightforward. Quoted to order against BOM quantities; availability confirmed at RFQ.","metaTitle":"1.5SMC150CA-M3/9AT Vishay TVS, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC150CA-M3/9AT bidirectional Zener TVS diode, 1500W peak pulse power, 128V standoff, DO-214AB SMC.
